Painting & Powder Coating

JM Precision has 2 sets of painting equipment and 3 sets of powder coating equipment

Adopt NADCAP Certification

Powder Coating Process Type

In JM Precision 10,000 grade dust-free workshop, keep constant temperature, humidity and clean air for a long time (air dust content < 10mg / M) ³) We have 2 sets of painting equipment and 3 sets of powder coating equipment, which are manually sprayed by our experienced and skilled spraying masters to ensure product quality and meet customer needs.

Paint Spraying

02

Powder Spraying

Paint Spraying

A method of dispersing uniform and fine droplets into the surface of the coated object through the spray gun with the help of air pressure. Usually, the spray gun is evenly sprayed on the surface of the object, which is water-resistant, oil-resistant and fast drying. It is used to paint cars, aircraft, wood, leather, etc.

In JM Precision 10,000 grade dust-free workshop, there are 2 sets of painting equipment. The painting equipment is flexible and can spray 360 ° without dead angle. It is manually sprayed by our experienced and skilled spraying masters to ensure product quality and meet customer needs. It is applicable to all kinds of metal processing parts and plastic processing parts, from CNC processing / sheet metal processing to painting processing, and we provide one-stop service.

Powder Spraying

The powder coating is sprayed on the surface of the workpiece with electrostatic powder spraying equipment. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; After high temperature baking, leveling and curing, the powder coating becomes the final coating with different effects.

In JM Precision 10,000 grade dust-free workshop, we have 3 sets of powder coating equipment, which adopts imported low-pressure high atomization spray gun and is sprayed manually by experienced and skilled powder spraying masters. The spraying quality is stable and can meet various customized needs of customers.

Technological Process

The painting process normally comes in 4 steps as listed below

01

Pre-cleaning

02

Electrostatic de-dust process

03

Painting or Powder coating

NADCAP Introduction

JM Precision’s anodizing process has passed National Aerospace and Defense Contractors Accreditation Program (abbreviation:NADCAP), which enables it to provide customers with high quality service.

NADCAP

It is a special process certification project in the aviation industry. It evaluates the process compliance of suppliers involved in special processes in the aviation supply chain through the operation mode of industry management.

 

NADCAP certification mainly involves heat treating, chemical processing, welding,nondestructive testing, composites, coatings, materials testing, non-conventional machining, shot blasting, conventional machining as a special process, sealants, elastic seal, fluid distribution system, measurement and inspection, etc.

 

At present, more than 50 world-renowned aviation manufactures including Boeing, Airbus, COMAC, GE, Rolls-Royce, Safran, UTC, Honeywell have joined and participated in the NADCAP project. Obtaining NADCAP certification has also become the entry threshold for opening the aviation market and entering the aviation supply chain.

 

PR is the only administrative party of NADCAP project in the world and is responsible for the daily operation and management of NADCAP project. All technical links of NADCAP certification, from the formulation of audit criteria and project operation.

Introduction to Quality Inspection

·In order to ensure the correct use of paint, it is necessary to manage the validity period of paint and powder; moreover, control the temperature and humidity of paint and powder warehouse is also needed;

·Kept 10,000 grade dust-free condition in painting workshop.

·In order to ensure the stability of the production process, the operation method of each coating shall be carried out according to the requirements of TDS documents, and the relevant parameters of each process shall be recorded in real time.

·In order to ensure that the sprayed film meets the requirements, relevant performance tests need to be done, such as Oxford film thickness test, hardness test (meeting ISO15184 & ASTM D 3363), adhesion test (meeting ISO2409), adhesion test (meeting ISO2431), impact test (meeting ISO6272-1), color difference test, gloss test and color matching of standard light source.

·All tests can meet ASTM B117 & ISO standards, or customized tests can be carried out according to customer standards.

01

Oxford Film Thickness Tester

Using the eddy current measurement principle, it can easily and nondestructive measure the paint, plastic, rubber and other coatings on non-ferrous metal substrates, or the thickness of anodic oxide film on aluminum substrates. It is widely used in machinery, automobile, shipbuilding, petroleum, chemical industry, electroplating, plastic spraying, enamel, plastics and other industries.

02

Taber Abraser

It is used to measure the wear resistance of materials, expressed by wear amount or wear index. Wear resistance is related to almost all properties of materials, and under different wear mechanism conditions, there are different requirements for material properties in order to improve wear resistance.

03

Color Difference Tester

It is widely used in the field of color management in plastic, printing, paint ink, textile and garment industries. According to the lab and LCH principles of CIE color space, the measurement shows the color difference △ E and △ lab values between the sample and the measured sample.

04

Gloss Meter

It is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials.

Powder Coating Advantage Of JM Precision
